Abstract
The cruise had the following scientific objectives: acquisition of high-resolution seismic data in areas with identified gas seepage sites in the Storbanken area to study the mechanisms controlling near-surface migration and seepage, complement the cross-disciplinary data repository by CAGE in this area, and searching for seafloor seepage sites based on regional structural features (e.g., fault lineaments, glaci-tectonic features).
